January 20

We have been exploring doubles (1+1, 2+2, 3+3, etc.). Today each child wrote as many doubles as possible during the Math lesson. Then we looked at some patterns that happen when we add doubles. Some children worked with material that helped them make doubles with "big" numbers (40+40, 100+100, 1000+1000, etc.).

Tomorrow we will continue our work with doubles, looking more closely at the patterns in doubles to 50+50.

Ask your child to show what (s)he knows about adding doubles. You can expect some misunderstandings at this point. When your child makes a mistake with doubles, see if you can figure out what misunderstanding created the mistake. Questions like, "Tell me now you know that," or "Show me how you did that," help your child to figure things out while feeling smart.
